Professor Dr. JOHANNES M. HENN

PRISMA Professorship for Mathematical Physics

In June 2015 Johannes Henn was appointed professor for Mathematical Physics at the Cluster of Excellence PRISMA, Department of Physics, Mathematics and Computer Sciences of the Johannes Gutenberg University in Mainz.  His research focuses on fundamental properties of gauge theories, the development of general methods for quantum field theory, and their applications to phenomenology of elementary particles.  

Johannes Henn conducts research in the field of particle physics with a particular focus on supersymmetric quantum field theories and their relations with string theory. His studies include the recently discovered dualities between scattering amplitudes, correlation functions of local operators, and Wilson loops. The aim of his research is to find new and currently hidden structures in the description of these objects at both weak and strong coupling.  

Johannes Henn studied in Augsburg and completed his main studies in France. At Lyon University he took on his doctoral studies graduating there in 2008; title of his PhD Thesis: "Duality between Wilson loops and gluon amplitudes".    

Through the appointment of Johannes Henn, the theoretical particle physics community in Mainz has been reinforced with an internationally highly respected scientist.
